• - Keep your bracelets with magnetic locks away from water to ensure that they stay fast and protect the locks from becoming oxidized.
• - Remove your jewellery before bathing. Accumulated soap diminishes gold’s color and lustre.
• - Chlorine can damage your ornaments. So, remember to remove all your ornaments before going for a swim.
• - Makeup, hair spray and perfumes cause dullness and loss of color. So always wear your ornaments last.

The diamond color evaluation of most gem-quality diamonds is based on the absence of color. A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value. GIA’s D-to-Z diamond color-grading system measures the degree of colorlessness by comparing a stone under controlled lighting and precise viewing conditions to masterstones of established color value.

To determine the cut grade of the standard round brilliant diamond – the shape that dominates the majority of diamond jewellery – GIA calculates the proportions of those facets that influence the diamond’s face-up appearance. These proportions allow GIA to evaluate how successfully a diamond interacts with light to create desirable visual effects such as:

• -Brightness : Internal and external white light reflected from a diamond
• -Fire : The scattering of white light into all the colors of the rainbow
• -Scintillation : The amount of sparkle a diamond produces, and the pattern of light and dark areas caused by reflections within the diamond

GIA’s diamond cut grade also takes into account the design and craftsmanship of the diamond, including its weight relative to its diameter, its girdle thickness (which affects its durability), the symmetry of its facet arrangement, and the quality of polish on those facets.

The GIA Diamond Clarity Scale has 6 categories, some of which are divided, for a total of 11 specific grades.

• -Flawless No inclusions and no blemishes visible under 10x magnification
• -Internally Flawless No inclusions visible under 10x magnification
• -Very, Very Slightly Included (VVS1 and VVS2) Inclusions so slight they are difficult for a skilled grader to see under 10x magnification
• -Very Slightly Included (VS1 and VS2) Inclusions are observed with effort under 10x magnification, but can be characterized as minor
• -Slightly Included (SI1 and SI2) Inclusions are noticeable under 10x magnification
• -Included (I1, I2, and I3) Inclusions are obvious under 10x magnification which may affect transparency and brilliance

Diamond carat weight is the measurement of how much a diamond weighs. A metric “carat” is defined as 200 milligrams. Each carat can be subdivided into 100 ‘points.’ This allows very precise measurements to the hundredth decimal place. A jeweller may describe the weight of a diamond below one carat by its ‘points’ alone. For instance, the jeweller may refer to a diamond that weighs 0.25 carats as a ‘twenty-five pointer.’ Diamond weights greater than one carat are expressed in carats and decimals. A 1.08 carat stone would be described as ‘one point oh eight carats.’ All else being equal, diamond price increases with diamond carat weight because larger diamonds are rarer and more desirable.
